  • Lacosamide


Lacosamide (Vimpat) is a newly licensed novel antiepileptic drug. We report a case of refractory convulsive status epilepticus (CSE) that was successfully controlled with lacosamide. The 38-year-old male patient was admitted for a series of complex partial seizures with secondary generalization leading to refractory CSE. During the transport to the hospital the patient was given 22.5 mg diazepam, 12.5 mg etomidate, and 5 mg midazolam without success. An additional dose of 4 mg lorazepam and a dose of 1,500 mg levetiracetam after admission were yet without clinical effect. A further treatment with lacosamide (300 mg via percutaneous gastric fistula) resulted in complete clinical remission of the epileptic activity within 30 min. The application of lacosamide resulted in cessation of CSE and was well tolerated. To our knowledge, this is the first case of successful treatment of refractory CSE with lacosamide. Further studies are needed to evaluate the safety and efficacy of lacosamide in treatment of SE.
